That sounds pretty awesome!

I think I just found one:

The error I got was:


\ Opening connection for arne@ftp using ssh
Tramp: Opening connection for arne@ftp using ssh...done
byte-code: Process died


Is it possible to adapt that error message so it states:


\ Opening connection for arne@ftp using ssh
Tramp: Opening connection for arne@ftp using ssh...done
byte-code: Process died. If this happens repeatedly, try

    `M-x tramp-cleanup-this-connection`


That would allow newbies to get out of the loop without killing the buffer.

I think as long as tramp in the buffer still blocks writes and the user does
not get told how he can exit the block, the bug still persists and closing it
would just close the eyes against an existing problem (or worse: look like it
was fixed without providing a solution).

But if the error could just tell the user how to fix the condition, that would
suffice for closing the bug, I think: The error condition would no longer
require new users to kill the buffer.

Does that sound like a reasonable approach to you?

Best wishes,
Arne
